Marines

In the early days of naval warfare, there was little distinction between sailors and soldiers on a warship. The oarsmen of Ancient Greek and Ancient Roman ships had to be capable of fighting the rowers of opposing ships hand-to-hand,^[1] though hoplites began appearing on Greek ships specifically for the boarding of enemy ships.^[2][3]

The Roman Republic was the first to understand the importance of professional soldiers dedicated to melee combat onboard of ships. During the First Punic War, Roman crews remained inferior in naval experience to the Carthaginians and could not hope to match them in naval tactics, which required great fleet maneuverability and tactical experience. The Romans therefore employed a novel weapon which changed sea warfare to their advantage — they equipped their ships with the corvus, a long pivoting plank with a beak-like spike on the underside for hooking onto enemy ships, possibly developed earlier by the Syracusans against the Athenians during the Sicilian Expedition of the Peloponnesian War. Using it as a boarding bridge, Roman infantrymen were able to invade an enemy ship, transforming sea combat into a version of land combat, where the Roman legionaries had the upper hand.^[4] During the early Principate, a ship's crew, regardless of its size, was organized as a centuria. Crewmen could sign on as naval infantry (called Marinus), rowers/seamen, craftsmen and various other jobs, though all personnel serving in the imperial fleet were classed as milites ("soldiers"), regardless of their function; only when differentiation with the army was required, were the adjectives classiarius or classicus added. The Roman Navy's two fleet legions, I Adiutrix and II Adiutrix, were among the first distinct naval infantry units.^[5][6]

The first organized marine corps was created in Venice by the Doge Enrico Dandolo when he created the first regiment of ten companies spread on several ships. That corps participated in the conquest of Byzantium (1203–1204), later officially called "Fanti da Mar" (sea infantry) in 1550., Venice also had dedicated naval expeditionary corps of naval infantry recruited primarily from Dalmatia from the local population called the Oltremarini (overseas troops) ^[7]

Later, Spanish King Carlos I assigned the naval infantry of the Compañías Viejas del Mar de Nápoles (Naples Sea Old Companies) to the Escuadras de Galeras del Mediterráneo (Mediterranean Galley Squadrons) in 1537, progenitors of the current Spanish Navy Marines (Infantería de Marina) corps, making them the oldest marine corps still in active service in the world.^[8][9]

The English noun marine is from the adjective marine, meaning "of the sea", via French marin ("of the sea") from Latin marinus ("of the sea") itself from mare ("sea"), from Proto-Indo-European *móri ("body of water, lake") (cognate with Old English mere ("sea, lake"), Dutch meer, German Meer, all from Proto-Germanic *mari).

The word marine was originally used for the marine-type forces of England; however, the word marine or marina means "navy" in many European languages, including Dutch, French, Italian, German, Spanish, Danish, and Norwegian. Because of this, exact one-word translations for the English term "marines" do not exist in many other languages (with the notable exception of the Dutch word marinier). This can lead to misunderstandings when translating. Marine forces in non-English speaking countries typically have names that translate in English to naval infantry or coastal infantry. In French-speaking countries, two phrases exist which could be translated as marine, "troupes de marine" and "fusiliers-marins"; similar phrases exist elsewhere, e.g., in Portuguese Fuzileiros Navais.

The principal role of marine troops is military operations in the littoral zone; operating from ships, they are trained to land on and secure key points to around 85 km (about 53 miles) inland, or as far as ship borne logistics can provide.^{[citation needed]}

Marine units primarily deploy from warships using boats, landing craft, hovercraft, amphibious vehicles or helicopters. Specialist units are also trained in combat diving/combat swimming and parachuting.

As well as amphibious operations, marine troops are used in a variety of other, naval roles. Stationed at naval bases or forming marine detachments on board naval ships, they also conduct small scale raiding, maritime boarding operations, security of naval vessels and bases, riverine and coastal missions, mess duty, and field day operations.

In addition to their primary roles, they perform other tasks, including special operations and land warfare, separate from naval operations; ceremonial duties and other miscellaneous tasks as directed by their governments.

The Argentine Marine Corps (Infantería de Marina de la Armada de la República Argentina or IMARA) is a part of the Argentine Navy. Argentine marines have the same rank insignia and titles as the rest of the navy, although enlisted personnel have their own parade uniform. The Argentine Marine Corps dates from 1827 when a single infantry battalion was raised. This was expanded in 1880, but seven years later, the corps was merged with the existing coast artillery, to form a Naval Artillery Regiment. A series of reorganizations followed until responsibility for coastal defense was passed to the Argentine Army in 1898. Between 1935 and 1938 the marines reappeared in the form of five battalions of Marine Infantry, serving both on board ship and in coastal defense fortifications. In 1968, the Infantería de Marina was reorganized as a separate corps within the Navy.^[10]

However, in 1868, as part of his naval reforms, then Commander Wilhelm von Tegetthoff abolished the Naval Infantry Regiment and the Naval Artillery Corps in favor of an enlarged and all-encompassing Matrosencorps as by that point, no marines had served aboard a ship for 10 years, and so from that point on, sailors not serving on active warships received infantry drills and took up naval infantry duties.^[34]

For several centuries, the Byzantine navy used the descendants of the Mardaites, who were settled in southern Anatolia and Greece, as marines and rowers for its ships. Emperor Basil I also established a separate marine regiment, 4,000 strong, for the central Imperial Fleet based at Constantinople. These were professional troops, and were counted among the elite tagmata. In the 1260s, when emperor Michael VIII Palaiologos rebuilt the navy, he recruited the Tzakones (settlers from Laconia) and the Gasmouloi (men of mixed Greek-Latin descent) as special marine troops. Despite the progressive decline and virtual disappearance of the navy, they remained active until the late Palaiologan period.

The marines saw action at the end of the year following the official end of the First Sino-Japanese War when they attempted to retake Nanbang Fort (南幫炮台) from Japanese forces after it was attacked on Christmas Day of 1895 by an attacking force of 30,000 Japanese with 6,000 Chinese defending the fort; which subsequently fell to Japanese forces on December 29, 1895. Being greatly outnumbered and lacking heavy weapons, the marines failed to dislodge the Japanese from the fort.^[35]

Following the 1911 Revolution and the collapse of the Qing dynasty's rule over China followed by its puppeting by the Empire of Japan resulting from Japan's 1931-1932 invasion of Manchuria as part of Japan's imperial expansion into China, the Japanese carved out the state of Manchukuo from the former territories of Manchuria for former Emperor of Qing China; Puyi, to rule over as a puppet Emperor of Manchukuo to Japan.

As a result of the surrender of naval assets in the region (then under the jurisdiction of the Kuomintang) under the command of Captain Yin Zuqian (尹祚乾) at Harbin as a result of the invasion, the ships Captain Yin surrendered (which at the time consisted of five river gunboats) eventually became the foundation of the Manchukuo Imperial Navy.

The Manchukuo Imperial Navy maintained a naval infantry force of 300 marines.^[36] The Manchukuo Marines (滿洲國海軍陸戰隊) were modeled after the naval infantry force of the former Beiyang Fleet's Marines.^[37]

Marineregimentet (The Marine Regiment) was the naval infantry of the Royal Dano-Norwegian Navy. Leading up to the Denmark–Norway union in 1814, the unit moved to Rendsburg and changed its name to Bornholm Infantry Regiment in 1741 and fell under the jurisdiction of the Royal Danish Army becoming a regular infantry unit. The Bornholm Infantry Regiment continued to exist until its disbandment in 2000.

The corps was founded on 10 December 1665 during the Second Anglo-Dutch War by the unofficial leader of the republic, Johan de Witt, and Admiral Michiel de Ruyter as the Regiment de Marine. Its leader was Willem Joseph Baron van Ghent. The Dutch had successfully used ordinary soldiers in ships at sea in the First Anglo-Dutch War. It was the fifth European marine unit formed, being preceded by the Spanish Marines (1537), the Portuguese Marines (1610), the French Marines (1622) and the English Royal Marines (1664). Like Britain, the Netherlands has had several periods when its Marines were disbanded. The Netherlands itself was under French occupation or control from 1810 until 1813. A new marine unit was raised on 20 March 1801 during the time of the Batavian Republic and on 14 August 1806 the Korps Koninklijke Grenadiers van de Marine was raised under King Louis Bonaparte. The modern Korps Mariniers dates from 1814, receiving its current name in 1817.

The battle honors on the Korps Mariniers' colors are: Raid on the Medway (1667), Kijkduin (1673), Sennefe (1674), Spain, Dogger Bank (1781), West Indies, Algiers (1816), Atjeh, Bali, Rotterdam (1940), Java Sea (1942), Java and Madoera (1947–1948), New Guinea (1962) and Cambodia (1992–1993).

The Meredessantpataljon, was a short-lived infantry battalion of the Estonian Navy. The battalion was created in 1919 from the crews of the Estonian surface warships and was based in Tallinn. The unit was mainly used on the Southern Front during the Estonian War of Independence. The unit was operational from March to June in 1919.

The Troupes de marine were founded in 1622 (as compagnies ordinaires de la mer) as land forces under the control of the Secretary of State of the Navy, notably for operations in French Canada. The Compagnies de la Mer were transformed in line infantry regiments by Napoleon, but became once more marine forces in 1822 (for the artillery) and 1831 (for the infantry). These Troupes de marines were in the 19th century the main overseas and colonial forces of the French military. In 1900 they were put under the orders of the War Ministry and took the name of Troupes Coloniales (Colonial Forces). In 1958 the designation of Troupes Coloniales was changed to Troupes d'Outre-Mer (Overseas Forces) but in 1961 it reverted to the original Troupes de marine. Throughout these changes in title, these troops continued to be part of the French Army.

The Federation of Gran Colombia Marines were formed in 1822 and were disbanded in 1829, Personnel were mostly from Venezuela.

• German Empire: During the German Imperial era, three ‘sea battalions’ or Seebataillone^[38] based at Kiel, Wilhelmshaven and Tsingtao were maintained. These units served intermittently as colonial intervention forces. The III Seebataillon at the imperial navy's east Asian station at Tsingtao was the only all-German unit with permanent status in a protectorate/colony. The battalion fought at the Siege of Tsingtao.
• Nazi Germany: The Marinestosstruppkompanie, was a naval infantry of Kriegsmarine in the Second World War.
• East Germany: The East German army's Nr29. Regiment ("Ernst Moritz Arndt") was a Motorized Rifle Regiment intended for amphibious operations in the Baltic Sea;^[39] while the Volksmarine Kampfschwimmer: Combat swimmer units were intended for support of amphibious operations and for raiding.^[40]

• At the time of the Iranian Revolution in 1979, the Imperial Iranian Navy had three battalions of marines.

• The old Ba'athist-era Iraqi Navy maintained several marine companies.
• The Iraqi Republican Guard maintained a Marine Brigade as part of its 8th As Saiqa Special Forces Division. The brigade was equipped with Brazilian-made Engesa EE-11 Urutu wheeled armored personnel carriers.

The Blackshirt militia maintained an independent Marine Group with four MVSN battalions (24th, 25th, 50th and 60th).

The Decima Flottiglia MAS was an Italian flotilla, with commando frogman unit, of the Regia Marina (Italian Royal Navy).

The 3rd Marine Infantry Division "San Marco" was an Italian division raised by Mussolini's Italian Social Republic.

During the feudal period, the Japanese used Ashigaru soldiers or regular Yumi archers as soldiers to protect ships from pirates. In 1873, a short-lived marine corps was added to the newly created Imperial Japanese Navy (IJN), using Britain's Royal Marines as a model. Considered unsuitable in its original form, the force was disbanded in 1878.^[41] The IJN’s land forces maintained several combat units:

• Special Naval Landing Forces were the Empire of Japan's professional marine corps.
• Naval Landing Forces were ad-hoc formations of IJN naval personnel formed into naval infantry units for duties ashore.
• The IJN also maintained the Guard Forces (keibitai) and Defense Units (bobitai), both of whom also received amphibious assault and beach defence training. However, their performance was poor or average when they were used as assault troops.
• The Imperial Japanese Army's 3,500 man Sea-Landing Brigades (1st to 4th) were used to conduct amphibious assaults on an island, but afterwards they stayed to garrison that island.

The role of Ottoman naval infantry originated in Orhan's conquest of the Karasi Beylik and the capture of its fleet. From then on, Janissaries and Azaps were sometimes deployed as marines during the 14th Century. The Deniz azaps were used during the 16th Century; while troops called Levend (Bahriyeli) were raised on and off over the centuries – over 50,000 of them by the late 18th century. The last raised units were the Ta'ifat al Ru'sa (corsair captains militia) recruited from among the North African Arabs and indigenous Berbers. Ottoman marines were part of the Ottoman navy.

Portugal raised numerous companies of Special Marines (Fuzileiros Especiais) and African Special Marines (Fuzileiros Especiais Africanos), both at home and in the African colonies of Portuguese Guinea, Portuguese Angola and Portuguese Mozambique, for service in Africa during the Portuguese Colonial Wars. The African Special Marines were all-black units.

Following the establishment of the Imperial Russian Navy in 1696 under Peter the Great, as part of his naval force expansion, Naval Infantry of the Russian Empire (морской пехоты Российской Империи) was formed on November 16, 1705, by using several regiments of marine equipage troops that fought as much on land as they served in ship detachments. One battalion was formed within the Guard, and served on the Imperial family's ships. The Imperial Russia's Naval Infantry have seen action in the Great Northern War during the Battle of Gangut, took part in the capture of Izmail fortress in the Russo-Turkish Wars, distinguished itself by defeating the Napoleonic Army in the Battle of Borodino, Battle of Kulm, and the Siege of Danzig as well as taking part in the amphibious operations in Naples during the Napoleonic War. The Naval Infantry also saw action in the Siege of Sevastopol during the Crimean War, and took part in the defense of Port Arthur during Russo-Japanese War. Its final campaign in World War I saw them deployed to the Baltic Sea to defend against the German attacks as well as the Caspian Sea for operations against the Ottoman Empire.^[42] During the Russian Civil War the Imperial Russian Naval Infantry was fractured as the men were divided and ended up joining both sides of the conflict. Naval Infantrymen who joined either the Bolsheviks (such as the Baltic Fleet Naval Infantry) or joined the Whites distinguished themselves in battle for their respective sides. Following victory of the Bolsheviks, surrendering White Naval Infantrymen were either shot on the spot, or were tortured before being executed. Those who sided with the Bolsheviks were absorbed under the banner of the Soviet Navy and formed the backbone of the new Soviet Naval Infantry. Some of these Soviet Naval Infantrymen, particularly members of the Baltic Fleet Naval Infantry who aligned with the Bolsheviks during the civil war would later take part in the 1921 mutiny against the Soviet government on the Kronstadt island fortress shortly following its winding down.

The Soviet Navy had a number of small battalion-sized naval infantry and coastal defence units that mostly served in the ports and bases before the Second World War. During the war, and building on the visuals of the mutinied sailors of Petrograd in 1917, the Stavka ordered formation of naval infantry brigades from surplus ship crew or shore duty sailors. Prior to World War II, members of the Soviet Naval Infantry took part in the 1921 mutiny against the Soviet government by the Baltic Fleet garrison on the Kronstadt island fort on the back end of the Russian Civil War. The mutiny was quickly put down by Soviet forces with retaliation against the rebels by the Soviet government resulting in their eventual execution.

The South Africa Marine Corps was set up as a subbranch of the South African Navy in 1979, with the primary purpose of protecting harbours. The Marines were disbanded in 1989, following a major restructuring of the Navy at the end of the South African Border War.

The oldest naval infantry. Created 27 February 1537 as Tercio de Armada by Carlos I (Charles V, Holy Roman Emperor 1519–1556). Miguel de Cervantes, famous writer, was a member of naval infantry at Lepanto Battle. Squadron General and Captain Diego Fernández de Medrano stood out in the front line during the conquest of Terceira Island in 1583. Medrano's galleys allowed for marine infantry to be used for the first time in order to occupy beaches and land.^[43]

In 2011, the UAE Marine Battalion was merged in the United Arab Emirates Presidential Guard.

• The Royal Marines date from the establishment of a Maritime Regiment of Foot in 1664. The Marine Regiments for Sea were formed in 1702 but by 1713 they had been disbanded or taken into the army as regiments of foot. In 1755, a permanent corps of marine companies was established for direct service under the Admiralty, and this force has an unbroken descent to the Royal Marines of today.
• The Royal Navy has since its beginning formed naval landing parties of seamen for action ashore, this being later formalised into the Naval Brigades. These brigades would often dismount guns from their parent vessels for use ashore, these guns often being the only artillery available. The most famous example of this form of land service was provided by the guns accompanying the forces relieving Ladysmith.
• The Corps of Colonial Marines was raised from former American slaves as auxiliary units of the Royal Marines for service in the Americas: Two of these units were raised and subsequently disbanded. The first was a small unit which existed from 1808 to 12 October 1810, the second was more substantial and existed from May 1814 to 20 August 1816.
• The Royal Naval Division was part of the Royal Navy in the First World War. In 1914, the shortage of ground forces for the Western Front led to the creation of the Division, composed of two brigades of sailors and a brigade formed by the Royal Marines. The Division was part of the Royal Navy but for command purposes was integrated into the army's command structure. The sailors were initially disappointing as infantry, but eventually developed into one of the better divisions. The Division participated in the defence of the Belgian city of Antwerp in late 1914, and then served with heavy casualties at the Battle of Gallipoli. At different times the Division included various army units. The division ceased to exist after the end of the First World War.
• Gooch's Marines,^[44] the 61st Foot, raised in the American colonies for the War of Jenkins' Ear in 1739. This was a 3,000 man American regiment of the British Army that served alongside British Marines. Among its officers was Lawrence Washington, half-brother of George Washington. It was disbanded as a regiment in 1742 and the remaining independent companies were merged with another regiment in 1746.

• American Colonial Marines were State Marines raised for the various state navies that came into existence shortly before the Revolutionary War.
• The Continental Marines were the marine force of the American Colonies during American Revolutionary War. The corps was formed by the Continental Congress on November 10, 1775, and was disbanded in 1783. The Continental Marines' first and only Commandant was Captain Samuel Nicholas.
• Hillet Marine River Regiment of the Union Army during the American Civil War, this regiment consisted of 10 rifle companies, a Cavalry Battalion of 5 companies, and an artillery battalion of three batteries, all of whom operated from Mississippi River gunboats as part of the Mississippi River Squadron.
• The Republic of Texas Marine Corps – Although a marine corps was suggested in the "Act and Decree Establishing a Navy," passed on November 25, 1835, it was not until acting governor James W. Robinson strongly urged the swift formation of such an organization in his message to the General Council on January 14, 1836, that steps were actually taken to commission officers of marines and recruit enlisted personnel. Before the end of the Republic of Texas and annexation to the United States, more than 350 men served with the Texas Marine Corps, and at least eighteen officers were commissioned to command them. The Texas Marine Corps served under the direction of the Navy Department of the Republic, and the duties of the corps were specifically ordained in fifteen articles passed by the Texas Congress on December 13, 1836. Marines served under their own officers aboard ship and ashore but were subject to the orders of the senior naval officer present. The uniform of the Texas Marine came from discontinued USMC stocks, changing only the buttons and cap devices to those of Texas configuration.^[45]
• The Confederate Marines were a branch of the Confederate States Navy and was established by the Confederate Congress on 16 March 1861; they were mainly (80%) defectors from the US Marines.^{[citation needed]}

The Nguyễn lords (ancestors of the Nguyễn dynasty) of southern Đại Việt maintained a small naval infantry or marine force. Each marine was referred to as a thủy binh (水兵) or water soldier.

Vietnamese dynasties had a long tradition of utilizing marines. This tradition went back no later than the Annam Protectorate of Tang dynasty when the governors built boats and trained marines to fight off pirates and invaders. The successive Vietnamese dynasties made full use of their marines' superiority at river and sea to launch successful campaigns against their northward and southward neighbors alike.

The forerunner of the Republic of Vietnam Marine Corps (VNMC) aka by their native name; Sư Đoàn Thủy Quân Lục Chiến (TQLC; Chữ Hán: 師團水軍陸戰) was established by Ngo Dinh Diem, then prime minister of what was then the State of Vietnam on October 13, 1954. It draws its roots from the colonial-era Corps des Marines vietnamien under the french’s Commandos Marine with much of their original members being Vietnamese who were trained by the Commandos Marine. Their establishment dates back to their formation as a naval infantry unit of the Republic of Vietnam Navy under the Vietnamese National Army, which after French decolonization, would become the Republic of Vietnam Military Forces. The TQLC was disbanded as a result of the fall of Saigon on 1 May 1975 marking the conclusion of the Vietnam War.

The 12th Naval Infantry Brigade (12. brigada mornaričko desantne pješadije) of the Yugoslavian Navy of the Socialist Federal Republic of Yugoslavia consisted of 900 to 2,000 men in three battalions. A multi-ethnic unit, the brigade was broken up during the dissolution of the Yugoslav federation and saw little action.
